A li ti fil d December 17, 1906- Serial No. 348,365.

To all whom it may concern:

Be it known that 1, WILLIAM J. BARR, a citizen of the United States of America, residing at Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in Electrically-Heated Sad- Irons; and I hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

This invention relates to improvements in electrically heated sad-irons, and pertains more especially to the provision of an electrically heated sad-iron with novel and meritorious protection for the cord by means of which the sad-iron is attached to a wall or other stationary object and which is employed in insulating and inclosing the two electric wires which participate in the connection of opposite terminals respectively of an electric source with opposite terminals respectively of the electro-heating resistance within the body of the sad-iron.

, This invention consists also in the provision of the sad-iron body with a handle-bearing top composed of asbestos or other material which is a good nonconductor of heat and electricity and having the handle removably secured thereto in such a manner that heat transmitted or radiating from the electro-heating resistance within the sad-iron-body shall not be transmitted to the handle.

This invention also consists in certain meritorious features of construction, and combinations of parts,

hereinafter described and pointed out in the claims.

a In the accompanying drawings, Figure 1 is a side elevation of an electric sad-iron embodying my invention, and portions are broken away and in section in this figure to moreclearly show the construction. Fig. 2 is a vertical section on line 22, Fig. 1, looking in the direction indicated by the arrow, and portions re broken away and in section in this figure to more cl arly show the construction. Fig. 3 is a horizontal section on line 3-3, Fig. 2, looking downwardly. Fig. 4 is a vertical section on line 4-4, Fig. 2, looking outwardly. Fig. 5

is a vertical section on line 55, Fig. 4, looking in the direction indicated by the arrow.

Referring to the drawings, A indicates the body of the sad-iron. The body A is provided interiorly (see Fig. 3) with an electro-heating resistance C which is constructed or formed in any approved manner and employed in heating the bottom or ironing surface of the body.

B represents the handle of the sad-iron. The body A is provided with a tap a which is composed of asbestos or other suitable material which is a nonconductor of heat and electricity. The top a is secured to the body A by suitably applied screws D. The top a covers the whole of the body A so that there is no liability of the handle becoming heated by the radiation of heat upwardly from the body. The top a completely insulates the whole of the handle B from the body A. The handle B (see Fig. 1) is removably secured to the top a by two screws E which are spaced longitudinally of the handle and extend from within the said top into the body and are screwed into the latter. The screws E have heads e countersunk within the under side of the top a, and the shanks of the said screws engage correspondingly threaded holes b formed in the handle. The heads e are covered at the inner side of the'top a with asbestos or any suitable cement or material (I which is a nonconductor of electricity and heat so that there is no liability of heat being conducted from the interior of the body A into the handle through the medium of the said screws.

G indicates a cord to which the sad-iron is attached and which is adapted to be attached to a wall or other stationary object and incloses and insulates the two wires Hand h employed in electrically connecting opposite terminals respectivelyof the electro-resistance G in the sad-iron-body with opposite terminals respectively of an electric source, not shown.

The Wires H and h are shown electrically connecting with and attached (see Figs. 2 and 3) to binding-posts K and 7: respectively which are attached to the rear end of the sad-iron-body and electrically insulated in anyapproved manner, as at I, Fig. 3, from the sadiron body, and opposite terminals L and l of the electro-heating resistance C are electrically connected with and suitably attached to the posts K and k respectively.

The cord G and the wires H and h inclosed thereby extend into the upper end of a casing F which is removably secured, by means of screws f, to the rear end of the sad-iron-body and protects the outer ends of the bind ing-posts and the connection of the said wires with the said posts.

A spring-connection is provided between the cord G and the sad-iron, and preferably comprises an upright spiral spring m which is arranged at one corner of the sad-iron-body. The spring m has its lower end (see Fig. 4) sprung or forced into and thereby is attached to an upright tubular member 1 formed upon a bracket R which is secured to the top a of the sad-iron-body preferably by one of the screws D employed in removably securing the said top in place. The spring m has its upper end (see Figs. 4 and 5) sprung or forced onto and thereby attached to the depending tubular member t of a clamp 'l" which is mounted on the cord G and (see Figs. 1 and 4) is provided interiorly with two holes ends of the said holes. Preferably the wire Q is in the form of a spiral spring which snugly embraces the cord Within the clamp T and is long enough to protect the cord at the ends of the holes 7 and 8 in the clamp.

The clamp T is split above its depending member t, as at 10, Figs. 2 and 5, vertically and centrally and longitudinally of the holes 7 and 8, and the clamping members thus formed at opposite sides of the split are caused to clamp the wire wound portion of the cord by tightening a screw 3 which engagescorrespondingly threaded holes formed in ears 12 which are formed upon A chain or flexible connection u (see Figs. 4 and 5) is arranged within and longitudinally pt the spring m and. attached at one'end to the depending member t of the clamp and at its other end to the tubular member 'r of the bracket R. The chain a has slack but not as much slack as the cord between the clamp and the sad-iron-body; The spring m forms a yielding connection between the cord and the sad-iron and takes up strain caused by twisting and jerking of the cord during the handlingof the sad-iron. The chain a has enough slack to accommodate the operation of the spring m, but limits the expansion of the spring, and the length of the chain is such that it preventsthe spring from expanding to such an extent as would bring an undue and destructive strain upon the spring. As the chain u has less slack than that portion of the cord extending between the clamp and the sad-iron-body it is obvious that when the chain becomes taut upon inadvertently permitting the maximum expansion of the spring by accidentally dropping the iron or otherwise the said portion of the cord will still have slack enough to prevent strain upon the attachment of the wires H and h to the binding-posts K and k. Were the sad-iron to drop from the ironing-board it will be observed therefore that the spring m and the chain u will participate in breaking the fall of the sad-iron; that the spring would first break the said fall, and that before undue and destructive strainwere brought upon the spring the fall would be further broken by the chain a.

The attachment of the chain it to the member 1* of the bracket R is preferably by the projection into the lowermost link of the chain of a tongue or projecting member 13 formed on the said bracket (see Fig. 4). The attachment of the chain a to the clamp T is preferably by the projection into the uppermost link of the chain of a tongue or projecting member 14 formed on and interiorly of the depending member t of the clamp (see Figs. 4 and 5).

It Will be observed also that the arrangement of the spring on in an upright position at one of the rear cornets of the sad-iron-body is important to arrange the spring-connection between the cord and the sad-ironbody out of the way of the handle of the sad-iron.
